RICHMOND -- A Daly City man who was shot several times while driving Saturday morning, then crashed his car into a Chanslor Avenue home and died was identified by authorities Monday.

Rodel Sarmiento, 43, was driving west on Chanslor about 8:30 a.m. when at least four shots were fired into his vehicle, hitting him and causing him to swerve off the road into the side of a house on Chanslor near 18th Street. No one in the house was injured, but Sarmiento was pronounced dead at the scene.

Despite the presence of thousands of revelers gathering just blocks away for the city's annual Cinco de Mayo parade on 23rd Street, no one has come forward as a witness to the shooting, Det. Nicole Abetkov said. No one reported the shooting to police, who arrived on Chanslor and saw the car crashed into the side of the house after ShotSpotter technology detected the gunfire that killed Sarmiento.

"It's still a major whodunit," Abetkov said. "There's still no witnesses, there's nothing. We're working against the grain on this one."

According to Abetkov, police do not know why Sarmiento was even in the Richmond area Saturday morning, and said that no Richmond residents have come forward to explain why he may have been there or to say that they know him.

The fatal shooting marks the ninth homicide of the year in Richmond. Police have not made any arrests, and no motive has been released in the shooting.

Anyone with information may contact Richmond police at 510-620-6613 or 510-232-8477. There is a $10,000 reward for information that may lead police to Sarmiento's killer.
